The Long Road to Reproducible Builds
summary
Debian's reproducible builds effort aims to make compiled packages byte-for-byte identical so anyone can verify binaries against source. They run a Jenkins test farm (67 jobs on seven hosts) that rebuilds ~1,300 packages twice to measure reproducibility (currently ~83%), use tools like strip-nondeterminism, diffoscope and Source Date Epoch, and rely on snapshot.debian.org to recreate environments; the infrastructure finds issues, generates patches and hundreds of bug reports (~644 existing plus ~100 new), and continuously validates fixes.
